No, it should be send only on change.

For monitoring of the device you can use heartbeat object or something similar. If you don't want change this repetition then you must create new object(could be virtual) and valve status must update its  value by grp.checkupdate() method, but there is no reason and if you are working in automation then you must learn how to right use devices and then trust them Especially if it is about LM

Thank you mate!
